The explanation for the dark matter (DM) content in the universe today is another motivation for the particle physics beyond the SM.
A huge number of models has been studied in the literature to include all types of candidates to the DM content like scalars, fermions, and gauge bosons [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}. The SM extension with the extra \(U(1)_{X}\)  is one of the
most well motivated models to include Dirac fermions candidate as a DM content [8]}, [9]}, [10]}.
The \(U(1)_{B-L}\)  added to a \(\mathbb {Z}_{2}\)  discrete symmetry includes stable Majorana RHNs that can be candidate to a DM content [11]}, [12]}, [13]}, [14]}, [15]}. In the 331 model, a \(\mathbb {Z}_{2}\)  discrete symmetry is added
to make one of the scalar physical fields stable and candidate to a DM content [16]}. In all these cases, a neutral gauge boson \(Z^{\prime }\)  or scalar fields with masses at the range 10 GeV - 10 TeV works as a DM portal connecting the SM fermions with the DM content.
